Principle of Operation
The SONOFF Smart RGB LED Bulb contains an integrated Wi-Fi module that connects directly to a 2.4GHz wireless network. Once paired with the eWeLink application, users can remotely control the bulb's power, brightness, color, and scheduling from anywhere with internet access.

The internal LED driver independently controls red, green, blue, and white LEDs to generate millions of color combinations as well as adjustable white illumination. Voice assistants communicate through cloud services, allowing users to change lighting settings using simple spoken commands.
The bulb can also participate in smart home automation routines, enabling automatic lighting based on schedules, sunrise/sunset, occupancy, or other connected smart devices.

Wiring
Installation requires simply screwing the bulb into any compatible E26 light socket and powering it with the appropriate AC mains voltage. The bulb is then paired with the eWeLink mobile application through the Wi-Fi network.
